I am working on a Yamaha XS850 Special, and the engine is very corroded. I wanted to know if anyone had a solution to removing the oxidation from the aluminum engine cases. I have tried using wire brushs and small round bristled brushs between the fins. This is a long and tedious process. If anyone has a better idea I am open to ideas. Unfortunately I do not have a blaster, or know anyone that has one.
